Description Usage Arguments Examples
This function calculates the values of valid moment combinations for two-step Generalized Method of Moments with user-defined types of time-dependent covariates, applied to longitudinal data with proportion outcomes. It allows for unbalanced longitudinal data, meaning subjects can be observed for different numbers of times. The function returns a vector "types" indicating validity of different moments conditions.
